Primary alkyl halides favor SN2 mechanisms because they have less steric hindrance compared to secondary or tertiary alkyl halides. The SN2 mechanism involves a single-step backside attack of the nucleophile on the electrophilic carbon, requiring good nucleophile and leaving group properties. Additionally, primary alkyl halides have better leaving groups, such as halides, which further favor the SN2 reaction pathway.

1 Show the primary structure of the polypeptide with the abbreviated structure of Gly-Phy-Trp-Val-His?
The primary structure of a polypeptide with the sequence Gly-Phy-Trp-Val-His is: Glycine-Proline-Tryptophan-Valine-Histidine.
When you mix primary colors you produce?
The following equations show what primary physical colours make secondary colours: Red + Yellow = Orange Yellow + Blue = Green Blue + Red = Purple Red + Yellow + Blue = Black No. Red, yellow, blue are *not* primaries. This is subtractive (printing) colorimetry, where the primares are yellow, cyan magenta. The following equations show what primary light colours make secondary colours: Red + Green = Yellow Green + Blue = Cyan Blue and Red = Magenta Red + Green + Blue = White Yes. This is additive, and the primaries are red, green, blue.
How can you distinguish aniline and primary amine?
Aniline is a specific type of primary amine that contains a phenyl group attached to the amino group. One way to distinguish them is by performing a diazo coupling reaction, where aniline will give a colored dye, whereas a simple primary amine will not show this reaction. Additionally, aniline can be distinguished by its distinctive smell and the fact that it can undergo aromatic electrophilic substitution reactions due to the presence of the phenyl group.
Chromic acid test in alcohols?
The chromic acid test is a chemical test used to distinguish primary, secondary, and tertiary alcohols. When chromic acid solution is added to an alcohol and heated, primary and secondary alcohols will oxidize to form aldehydes or ketones, producing a color change (orange to green). Tertiary alcohols do not undergo oxidation and will not show a color change.
How could you set up experiment to show evidence of evaporation?
Leave water in a dish in the sun, place a clear plastic sheet several centimeters over the dish in a tent-like shape, and have another dish on both sides of the primary dish. The water from the primary will end up in the collection dishes because the water will evaporate and then be stopped on the sheet, and drip in to them.
Why williamsons synthesis show SN2 mechanism?
Williamson's synthesis of ethers involves the reaction of an alkyl halide with an alkoxide ion. The alkoxide ion acts as a strong nucleophile, attacking the electrophilic carbon in the alkyl halide to displace the halogen in an SN2 fashion. This results in the formation of an ether product.
Why cannot aromatic primary amines be prepared by Gabriel phthalimide synthesis?
Aromatic primary amines cannot be prepared by the Gabriel phthalimide synthesis because the nitrogen atom in the aromatic primary amine is not sufficiently nucleophilic to displace the phthalimide leaving group. The reaction typically requires a primary alkyl halide, which is more reactive toward nucleophilic substitution than an aromatic primary amine.
Why did they use chemicals and glass plates in early photography?
until celluloid was invented Glass plates were used because it was the only way to suspend the emulsion evenly and allowed light to pass through. It was easier to handle. Some glass plates were large and were put into contact with paper to create a positive image. Chemistry was used to convert the silver halides in the emulsion to visible black metallic silver halides. When light was shone through the glass the black metallic silver halides stopped the light and the paper was exposed where the light pass by the halides. This caused the material being exposed to show a positive image.

Why alkyl group is an electron donating group when attached to a pi system please explain?
Alkyl groups show an effect called hyperconjugation. This is essentially the overlap of sigma bonds that are parallel to pi bonds/carbocations. The electron cloud from the hydrogen and carbon sigma bonds is able to coordinate with a pi system that is perpendicular to it. This makes the alkyl group indirectly resonance donating. You have to do some imagining to see the hyperconjugation. If you need help, get a molecular modelling kit or ask your professor.

Why silver halides show frenkel defect?
Silver halides, such as AgCl, AgBr, and AgI, exhibit Frenkel defects due to the small size of silver ions compared to the halide ions. In a Frenkel defect, a cation (in this case, Ag+) is displaced from its lattice position and occupies an interstitial site, creating a vacancy in its original position. This defect is favored because it allows for the accommodation of the smaller silver ions without significantly distorting the crystal lattice. As a result, Frenkel defects enhance the ionic conductivity of silver halides, making them useful in various applications, including photography and as semiconductors.

How can tell if an alcohol is primarysecondary or tertiary using lucas test?
The Lucas test distinguishes between primary, secondary, and tertiary alcohols based on their reactivity with hydrochloric acid in the presence of zinc chloride. Tertiary alcohols react quickly, typically within minutes, to form an insoluble alkyl chloride, while secondary alcohols take longer (several minutes to hours) to react. Primary alcohols show little to no reaction under the same conditions, remaining clear. Thus, the speed and extent of the reaction indicate the type of alcohol present.
